3-Phase Inverter Duty Motor 30kW 40Hp

The 3-Phase Inverter Duty Motor 30kW 40Hp is an electric motor integrated with advanced inverter technology, allowing changes in input voltage and frequency, thereby flexibly controlling rotational speed according to operational needs. With powerful capacity, stable performance, and energy-saving capability, the inverter duty motor is considered an ideal choice for production lines and heavy-duty systems that require high precision and durability.

Overall design of the 3-phase 30kW 40Hp inverter duty motor

The inverter duty motor is manufactured on a modern production line, using a thick, sturdy, one-piece cast-iron housing that withstands heavy loads and reduces vibration during operation. An industrial electrostatic paint layer covers the entire body, enhancing oxidation and rust resistance while protecting the motor in humid, dusty, or mechanically stressed environments.

An independent forced-cooling fan is integrated at the rear of the motor, providing rapid cooling efficiency and ensuring a stable temperature throughout operation, even when the motor runs under heavy loads at low speeds.

Detailed structure of the inverter duty motor

The 3-Phase Inverter Duty Motor 30kW 40Hp is a 3-phase electric motor with the following main components:

• Stator: Uses pure copper wire with high electrical conductivity, reducing heat loss and creating a strong magnetic field.
• Rotor: Made of tightly assembled electrical steel laminations, increasing lifespan and maintaining stable performance.
• Terminal box: Separately arranged with a main power connection box and a separate box for the forced cooling fan.
• Forced cooling fan: Generates a powerful airflow, operates continuously, and maintains optimal heat dissipation for the motor.
• Inverter circuit: Converts alternating current into a variable-frequency current, thereby precisely adjusting speed and torque.

Guide to wiring a 3-phase electric motor

Step 1: Open the terminal box cover

• Use a screwdriver to remove the 4 screws on the terminal box cover of the electric motor and open the cover.

Step 2: Connect the 380V power wires to the terminal block

• Bring the 3-phase power wires (380V) inside the motor terminal box.
• Attach each power wire one by one to the 3 corresponding contact studs on the terminal block. These studs are labeled: U1, V1, and W1 respectively.
